Is it not possible to make a program be both a client & server? I'm new to the winsock control & just finished reading PINO's basic intro. I did the peer-to-peer project for client/server chat. However, I want the program to be both a server & a client so two people don't have to worry about one being the server & one being the client.

I have the code for the program to listen. However, when I put the code for it to make a connection & click the button for that code, it states "invalid operation at current state".

So is it possible to have a program be both a client & server? I think it is and maybe it needs 2 winsock controls? Any help is greatly appreciated.
